Abstract :
The operation of a four-quadrant electronic controller for a switched-reluctance motor is described. The controller uses signals from a three-phase magnetoresistive shaft-rotation sensor to produce synchronised gating signals for the control of stator winding currents. A speed-dependent signal derived from the sensor output adjusts the timing of the gating waveform to maximise the torque produced. Measurements on a 1 kW machine are presented
